DESCRIPTION:Speakers: Clement Sichangi (University of South Africa)\nPhoto
 transferred thermoluminescence (PTTL) is the transfer of optically stimula
 ted electrons from deep saturated electron traps to previously emptied sha
 llow electron traps. Conventional thermoluminescence (TL) of CaGa2O4:Pr3+ 
 shows five peaks of which only three are Phototransferred under illuminati
 on by blue light (470nm) for TL measured to 500 oC. Pulse annealing analys
 is shows all PTTL peaks as acceptors of electrons from their successful tr
 aps. Analysis of very deep traps reveals only two peaks are acceptors to t
 raps beyond 500oC\, one of which is not observed for preheating below this
  temperature suggesting competition from other traps. No PTTL peak observe
 d for preheating beyond 630 oC suggesting absence of deep traps beyond thi
 s temperature. The effect of illumination time is analyzed for each PTTL p
 eak. Control studies without illumination shows no peak reappearance after
  it is cleared by preheating. These great properties are good for home lig
 hting\, dosimetry and light in the dark materials.\n\nhttps://events.saip.
